## MathQuill Unit Vectors

Does anyone know how I can get unit vector notation in the mathquill equation editor in the new quiz engine?  It doesn't seem to recognize \hat{i} or \uvec{i} as latex does.

It's annoying because it is supported in the RCE when editing a regular page.  The best work-around that I'm using is to use the text  "r-hat" . You can also create the unit vector in the regular RCE then copy it as an image then put the image where you need it. Both are terrible workarounds.)

That link has a freakish amount of information on writing latex in Canvas. Very easy to read. I hope this is helpful.

In an attempt to answer your question if you wanted to write ray AB you could use $$\overrightarrow{AB}$$ that inputs nicely. The component vectors could be written as $$\langle$$. The \vec in mathquill does not look pretty as the arrow does not increase in length.

I couldn't find a way to add a harpoon over a letter to represent a vector. Canvas seems to have no solution to this.
